Structure of Bone

In this video learn how to turn a bone into rubber! Learn how it is done and learn why it happens in this in this science video. The experiment uses a chicken bone and vinegar. An explanation is provided after the experiment. Run time 01:04.

In this video we look at the different types of bones: flat bone, short bone, long bone, etc.. This is Lesson 3 in The Skeletal System series. This is part of our Anatomy and Physiology lecture series. (05:17)

In China a painful surgical procedure called "bone stretching" can make people taller...but is it worth the risk? In this video, the reasons people choose this elective procedure are discussed. It also explores why this is such a dangerous procedure ...and how it is done. Grades 9-12. 3:31 min.[more]

Very detailed description of bone anatomy. Good pronunciation of unfamiliar terms. Computer generated voice is used to explain the images in the video. Very limited animation, but detailed diagrams. Grades 9-12. 1:16 min.

From DragonflyTV. Kobel and Nathan have a friend, Adam, who took a skateboarding spill and is stuck with a cast on his leg for weeks. So the boys head to the Oregon Museum of Science and Industry, and learn that scientists are using nanotechnology to... help regenerate nerves and bones. The nanomaterial keeps the bone together (without a cast) and slowly disappears as new bone grows and takes its place. The boys experimented with different mixtures and put their sponge bones to the test in the bone crusher to find out which mix made the strongest repair. They tested the following mixtures: all nanotubes, all minerals, 10% minerals, 30% minerals and 50% minerals.[more]

This video explains why bones get weaker with less gravity. It also describes how to prevent bone loss in space. The video explains how osteoclasts in our bodies eat away damaged/cracked bones and osteoblasts build the bone back up—a process known ...as remodeling. In space, this process is altered and osteoblasts do less building while osteoclasts eat away more bone. Scientists, doctors, and engineers are working hard to find ways to keep bones healthy in space. Exercise is an important countermeasure to help keep bones healthy in space. (5:52)[more]
